我正在尝试将绘图嵌入到Splitter窗口的右面板内，如何在绘图仪窗口内添加绘图。请在此处找到数据集的链接。https://www.dropbox.com/s/ncy6dlpm79p578s/Dataset.zip?dl=0。该文件包含波长和反射率的行和列。

如何在分割器的右面板内插入绘图窗口。
我不是100％确定我了解您的代码-肯定有一些格式和缩进问题。我也对asciitable不熟悉。但是，也就是说，可以将wxmplot.PlotPanel或ImagePanel嵌入使用拆分器的wxPython框架中。一个示例可能看起来像下面的代码。我尝试使它简短，但也尝试使用普通的wxPython使它完整。对于更完整的应用程序，您可能希望将读取数据文件放入一个单独的类中，依此类推。无论如何，这将使用您的Dataset文件夹，并且应该可以用来显示这些概念：
